Portfolio overview

Topcon Corporation has been granted 680 US utility patents between 2015 and 2025, placing Topcon Corporation at rank #660 across all assignees tracked by PlainPatent. This portfolio spans 83 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.9 claims per patent with primary concentration in G01C (MEASURING DISTANCES, LEVELS OR BEARINGS; SURVEYING; NAVIGATION; GYROSCOPIC INSTRUMENTS; PHOTOGRAMMETRY OR VIDEOGRAMMETRY). As a Foreign Corporation, Topcon Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Topcon sits between Yale University (685 patents, rank #656) and Aisin AW Co., Ltd. (674 patents, rank #664) - the closest US assignees by grant volume. The composite Innovation Score of 59.6/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 393 grants, compared with 287 in the 2015–2019 window, a +37% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Topcon Corporation's 10.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 83 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Topcon Corporation against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
